半球透镜馈源收发集成新月透镜天线 Hemispherical lens antenna feed transceiver integrated meniscus lens

技术领域 FIELD

[0001] 本发明涉及天线,尤其涉及一种半球透镜馈源收发集成新月透镜天线。 [0001] The present invention relates to an antenna, particularly to a hemispherical lens antenna feed transceiver integrated meniscus lens.

背景技术 Background technique

[0002] 国际上很早就对透镜天线系统开展了一系列的研究,传统的透镜天线一般采用平面、球面、双曲面、抛物面等几何形状,但是这些方法扫描范围有限,损耗大、工作频带窄,不能满足现代毫米波系统应用的要求。 [0002] International long lens antenna system carried out a series of studies, the conventional lens antenna is generally planar, spherical, hyperboloid, paraboloid geometry, but these methods are limited scanning range, a large loss, narrow operating band , millimeter-wave systems can not meet the modern requirements of the application. 密歇根大学的Prof.GMRebeiz所带领的研究组最早开创了介质透镜的研究领域(D·F.Filipovic,S· S·Gearhart and GMRebeiz,“Double-slot antennas on extended hemispherical and elliptical silicon dielectric lenses,''IEEE Trans Microwave Theory Tech.,MTT-41,pp.l738_1749,0ct.l993)。他在1994年提出了一种特别适合于毫米波段工作的介质透镜天线,它由一个半球和一段柱形延长段组成,其馈电天线可以很简单地集成在透镜的焦平面上。调节柱形延长段的长度可以微调透镜的焦距,在单波束应用的时候,一般调节柱形延长段的长度使得天线的增益达到最高。而在多波束应用的时候,则要求使得每个波束的增益均匀性达到最优,与单波束应用相比,这时候每个扫描波束的增益会有大概2〜3dB的下降(DFFilipovic,GPGauthier, S.Raman and GMRebeiz,u〇ff-axis properties of silicon and quartz dielectric lens antennas,''IEEE Trans.Antennas Prof.GMRebeiz University of Michigan research team led by first creating a research field dielectric lens (D · F.Filipovic, S · S · Gearhart and GMRebeiz, "Double-slot antennas on extended hemispherical and elliptical silicon dielectric lenses, '' IEEE Trans Microwave Theory Tech., MTT-41, pp.l738_1749,0ct.l993). he proposed a millimeter wave band is particularly suitable for the working of the dielectric lens antenna 1994, it is extended by a section composed of a hemisphere and a cylindrical section which feed the antenna can easily be integrated on the focal plane of the lens. adjusting section may extend the length of the cylindrical lens has a focal trimming, when the single beam applications, extending the length of the cylindrical segment generally adjusted so that the gain of the antenna to achieve highest. and when the multi-beam applications is required so that the gain of each beam uniformity optimal, compared with the single-beam application, this time there will be a gain for each of the scanning beam 2~3dB probably decline (DFFilipovic, GPGauthier, S.Raman and GMRebeiz, u〇ff-axis properties of silicon and quartz dielectric lens antennas, '' IEEE Trans.Antennas and Propagation,AP-45,No.5,pp.760-766,May 1997) 〇 and Propagation, AP-45, No.5, pp.760-766, May 1997) square

[0003] 上述介质透镜天线在高增益应用的情况下,重量会大大增加,给实际应用带来巨大困难,这时可采用新月透镜天线系统,这种天线系统分为馈源天线和双椭球面透镜两部分组成,当馈源天线的相位中心与双椭球面透镜的焦点重合时,由馈源天线辐射产生的电磁波通过双椭球面透镜将变为平行波束辐射出去,故可以很方便地实现高增益(X.Wu, GVEleftheriades and TEvan Deventer,“Design and characterization of single and multiple beam mm-wave circularly polarized substrate lens antennas for wireless communications,''IEEE Trans.Microwave Theory Tech.,MTT_49,pp·431-441, March 2001)〇 [0003] The dielectric lens antenna in the case of high gain applications, would greatly increase the weight, enormous difficulties in practical application, can be employed when meniscus lens antenna system, the antenna and antenna feed system is divided into oval-bis two-part spherical lens, when the focal point of the antenna phase center of feed with a double ellipsoid lens coincides feed antenna by the electromagnetic radiation generated by a double ellipsoidal lens into a parallel beam is radiated, it is possible to easily achieve high gain (X.Wu, GVEleftheriades and TEvan Deventer, "Design and characterization of single and multiple beam mm-wave circularly polarized substrate lens antennas for wireless communications, '' IEEE Trans.Microwave Theory Tech., MTT_49, pp · 431-441 , March 2001) billion

[0004] 然而,新月透镜的焦点只有一个,在馈源天线的相位中心与新月透镜的焦点重合时增益最高,现有的新月透镜天线不在焦点上的其他波束增益比焦点处的波束增益低,导致在多波束应用场景下,扫描角度越大,增益越低,旁瓣越高,波束宽度越宽。 [0004] However, only a meniscus lens focal point, at the focal point of the phase center of feed antenna meniscus lens coincides with the highest gain, the conventional meniscus lens antenna beam gain is not other than the focal point on the focal point of the beam low gain, resulting in a multi-beam application scenario, the larger the scan angle, the lower the gain, the higher side lobes, the wider beamwidth. 这种新月透镜在偏焦波束的性能较差,在实际应用中会带来困难。 This meniscus lens in the beam focus offset poor performance in practical applications bring difficulties.
